STOVE-PIPE.

SPECIFICATION forming part of Letters Patent No. 311,143, dated January20, 1885.

Application filed May 10, 1884. (No model.)

I 0 all whom it may concern:

Be it known that I, HENRY M. PIOKERING, of Holliston, in the county ofMiddlesex, State of Massachusetts, have invented a certain new anduseful Improvement in Stove- Pipes, of which the following is adescription sufficiently full, clear, and exact to enable any personskilled in the art or science to which said invention appertains to makeand use the same, reference being had to the accompanying drawings,forming a part of this specification, in which Figure 1 is a sideelevation representing my improved stove-pipe in use, and Figs. 2, and 3vertical longitudinal sections of the pipe detached.

Like letters of reference indicate corresponding parts in the differentfigures of the drawings.

In setting up ordinary base-burning or diving-flue stoves muchdifficulty is frequently experienced on account of the funnel-hole inthe rear or standing pipe of the stove and that in the chimney varyingin height, thus necessitating the use of a knee or bend in the funnel,and greatly increasing the expense of properly connecting the stove withthe chimney.

My invention is designed to obviate this difficulty; and to thatendlmake use of means which will be readily understood by all conversantwith such matters from the following explanation, the extreme simplicityof theinvention rendering an elaborate description unnecessary.

In the drawings, A represents the stove, B

the funnel, and O the back or standing pipe.-

This pipe is provided with an elongated slot, at, and is arrangedvertically in parallelism with the body of the stove, its lower endresting on the base d, and its upper being connected to the stove by theshort horizontallyarranged pipe at, having the damper o, in the anydesired position. The flange m is of sufficient length to cover the slotat when the sleeve D is dropped to its fullest extent, the body of thesleeve being long enough to cover said slot when raised to the highestpoint, or so as to bring the shoulder h against the lower side of thepipe-collar Z on the pipe 0.

It will be obvious that my improvement will enable the pipe-collar z ofthe stove to be readily adjusted to correspond with the thimble orfunnel-hole in the chimney, when said hole is arranged at any of theusual distances from the floorfor instance, from eighteen to thirtyinches-and that, when the funnel-hole in the chimney is near theceiling, necessitat ing the use of a vertical funnel, B, to make theconnection, it will also greatly assist in properly coupling the pipe.

I am aware that a patent was granted to one Bell, March 12, 1861, No.31,652, for an improvement in stove-pipes; but my invention isessentially different from his, and I do not, therefore. claim anythingshown or described in said patent. In said patented pipe there is a boxclosed at both ends and fitted with flanges to receive a flangedpipe-collar. This box cannot be readily cleared of ashes and soot, iscomparatively expensive to construct, and its flanges are liable to getbent and out of order, thereby preventing the collar from being readilyadjusted. In my device the standing pipe of the stove is slotted andprovided with a flanged sleeve, which is fitted to slide thereon in sucha manner as to be retained by friction in any desired position, therebyenabling the eduction or chimney pipe to be readily adjusted vertically,

simplifying the'construction and rendering the apparatus less expensiveand more durable.

Having thus explained my invention, what I claim is 1. The pipe 0,provided with the pipe-collar Z and slot at, and the sleeve D, providedwith the pipe-collar z and flange m, constructed, combined, and arrangedto operate substantially as set forth.

2. The stove A, having the pipe 0, provided with the slot 00, incombination with a sleeve carrying a pipe-collaraud adapted to beadjusted vertically on said pipe, substantially as and for the purposespecified.
